Setting up dynamic playfiled

[Brian Beuken]

Not so much a mistake as a confusion, when you have got your photoframe up and running, we are getting ready to start work on a proper game using a dynamic buffer, the code for this is explained in page 68-77. You can add this code to your photoframe example and get it up and running with not too much effort, but really its just explaining the code you will be downloading to use in Chapter 5, so typing it all in is optional. I should have made that clearer.
